Things To Check Before Getting One
Before you choose a water filter, you need to examine it closely to ensure it meets your unique water filtration needs. The following factors will help you pick the best RV water filter for your water purification needs.
You might have already noted that different water filtering systems come equipped with varying filter materials. Let’s outline the most common types of filters below to help you choose the most suitable one for you:
Carbon filters are among the most popular types used in the recreational vehicles. Filters with this type of filtering material remove not only particles but various water contaminants to improve the taste and smell of your drinking water. The carbon filters are available in up to 3 types—granular activated, modified carbon block, and solid block. The granular activated is the least priced of the three but still does a great job at purifying your camper water.
As you can easily tell from its name, this type of filter works by trapping the particles in your water/ These types of filers have different filtration capabilities and are rated depending on the size of particles they can trap in terms of microns. A micron translates to a thousandth of millimeter. The smaller the micron rating, the finer particles the filter can remove in water.
The main benefit of installing this type of filter in your camper is that it’ll help prevent clogging of your plumbing lines and appliances that use water. However, you need to know that it requires more maintenance than the other types of filters.
A ceramic filter features small holes that enable it to trap various contaminants in water, including sediment, bacteria, protozoa, giardia cysts, and more. This makes it the perfect choice if you want to flush out biological pests in water entering your camper.
Unfortunately, ceramic filters aren’t as effective in getting rid of chemical contaminants in your water. For this reason, manufacturers usually use them alongside carbon filters to boost their filtering efficiency and performance.
Source of water supply
Where are you getting the water you’re planning to run through your new filtration system? If you’re simply hooking up your RV to the campground water supply, then you should consider getting an in-line water filter. If you only need to fitter out your faucets or the water supply inside your RV, a compact canister filter is your ideal choice. It’s pretty compact, light, and won’t take up space in your RV.
Ease of installation/use
Make sure you choose a water filtering unit for your recreational vehicle that’s easy to setup. If you’re not careful when moving through the numerous options at the market, you can come across a model that’s a real pain to install.
Remember, you’ll be replacing the filter every 3-12 months, so you want to ensure the replacement process is always a breeze for you.
Look for a water filtration system that comes with a detailed instructional manual on how to set it up from start to finish. The usage and maintenance of the unit should also be easy for you.
One more thing you should keep in mind when shopping for an RV water filtration system is its physical size and storage. The perfect unit should be able to store in the available space in your RV. Generally, RVs have limited space, so you need to keep this factor in mind. You don’t want to end up buying the huge, heavy water filtration systems that are awkward to store in your recreational vehicle.
Pro Tip I: How much water do you plan to filter?
If you want to get a water filtration system that meets your specific water purification needs, then you’ll need to take into account the amount of water you plan to filter.
Some RVers opt to purify all the water running into their RV system while others are only interested in purifying drinking water.
By identifying which of the two groups above you fit in, you will have an easy time choosing RV water filtering system with the right capacity to meet your unique water purification needs.
Pro Tip II: How long are you planning to live in your RV?
As you already know, RV water filters don’t last forever. They need to replace every few months for continued effectiveness at eliminating undesired contaminants in water. Consider stocking enough filters or bringing backup replacement filters with you if you plan to go RVing for an extended period of time. This will ensure you don’t run out of clean drinking water when you’re in the middle of nowhere.
Which RV filtration system removes salt?
If you’re looking for a water filter system for s that removes salt, this is your part.
One thing you should keep in mind is that not all filtering systems can remove salt (sodium) from your water. For instance, carbon filters—the most popular types of filters for RVs—can’t get rid of sodium from water. Although some manufacturers will mislead you into thinking that these filter are capable of removing salt from your water, you shouldn’t fall into the trap.
With that said, we researched on the filtration systems that actually remove sodium from water and found the three top types listed below:
1. Dual stage filtration system
Dual stage filters utilize filtration and ion exchange to purify your water, making them a great option for removing slat form your water. Not just sodium, they also remove heavy metals and chlorine. But they leave traces of healthy minerals such as potassium.
If you install a dual filter system in your RV today, the water will be passed through two carbon filters and then to a tube connected to faucet line. The result is 100% clean and great tasting water, minus salt and other impurities.
Keep in mind that these types of filtration system are intended for under the sink or countertop installation. They’re also incredibly easy to use and maintain. However, you’ll need to hire a professional to do the installation for you.
2. Reverse osmosis filtration system
Reverse osmosis systems are also great at removing sodium from your recreational vehicle drinking water.
They work by utilizing pressure to force the water through a membrane filter that traps everything in the water and ONLY allows water molecules to pass. The water first passes through carbon pre-filter to trap organic materials and chlorine that may otherwise damage the membrane. They remove not only salt (sodium) but also barium, arsenic, hard metals, and a variety of other impurities.
Once the filtration is done, the filtered water passes to your RV faucet while the rest (water concentrated with impurities) passes down the drain.
It’s important to keep in mind that reverse osmosis systems are intended for plumbing-in with permanent connection to existing water pipe. They cost more than other types of filters and require replacement filters that are also quite pricey.
They also deliver high waste water ratio. For every 5 gallons of water you filter with a reverse osmosis system, you can expect around 40-90 gallons to be sent down the drain as waste water.
3. Distillation filtration system?
Ever heard about distillation filtration system? Well, this is a type of filter that boils your water to produce steam which is then blown into a separate cooling chamber with the help of a fan.
You can also trust this type of filter to remove sodium (salt), heavy metals, microbial contamination, pesticides, and many other contaminants in your water.
You’ll have various sizes to choose form when it comes to distillation filters…from the small batch processor (the size of a coffee cup) to a larger under sink continuous flow unit.
However, keep in mind that this filtering system removes all the minerals in your water, including the healthy ones. Since it uses electrical energy to boil your water in a process that takes around 7-8 hours, you can expect your energy bills to go up.
How to keep RV water filter from freezing?
RVing in freezing weather has its share of problems, among them…the high risk of water filters for RVs getting damaged.
Luckily, you can put a few measures in place to enable your water filter to survive through the harsh winter weather without sustaining any damages.
These measures include:
1. Completely empty your filtration system
One of the most effective measures you can take to prevent your water filter from getting damaged by winter weather involves emptying it completely before the freezing begins. This will ensure that the freezing doesn’t catch up with water in your in-line filter or cartridge and cause the water inside to freeze. Besides preventing damage, this will also help prevent huge water messes in your recreational vehicle when the water inside warms up.
2. Bring in your filtration system
If you’re using a cartridge filter system, leaving it outside will make it highly vulnerable to freezing weather. This will cause it to develop micro-cracks in its mechanical structure. These allows large particles to easily pass, compromising the filter’s efficiency. We, therefore, suggest that you bring it in your RV (and make sure it’s fully emptied).
3. Insulate your filter
Another great way to keep your RV water filter from freezing up involves warming it up. If you’re using a canister filter, you can keep it in an insulated box to keep it safe from freezing and the mess that comes with it. If you have filter situated outside, your travel trailer, then you may consider using an old ice chest with shop light inside to insulate and protect it against freezing.
4. Keep the water running
Yes, if you keep the water running in your RV installed faucets, water will keep flowing in the filtration system and the possibility of freeze-up happening in your RV will fall next to zero. This idea is based on the fact that, if water is moving constantly, it’s at a much lower risk of freezing when expose to extremely low temperature.
5. Winterize your
What if you want to store your recreational vehicle in the freezing winter months? Well, in this case, winterizing the vehicle will help protect your water filtration system as well as other appliances and equipment that can be damaged by freezing.
For starter, winterizing an RV simply means preparing it for the cold weather conditions. The largest part of winterizing your camper involves preparing the plumbing system by draining all the water in the system, including the water heater and storage tank, filling all the pipes in your RV with non-toxic antifreeze solution
NOTE: It’s recommended to always go through your RV user manual before you attempt any winterizing to help you understand any wintering instructions specific to your camper model.
Frequently Asked Questions
Q: How long will my RV water filter last?
